HEATER FOR enumerates AND THE LIKE.

Application filed July 22 This invention relates to an improved heaterfor curling irons and the like, and its objects are the provision of agenerally improved and simplified device for delivering the properamount of heat to the iron or irons to maintain them at a generallyuniform temperature and against overheating and a device adaptedforplural useby operators at opposite ends ordifferentpositions and inwhich theradiation loss is small and the current consumption relativelylow.

The invention is illustrated in the accompanying drawings, in which: P s

Figure 1 is a perspective View of anembodiment of the invention showinga pair of irons in position'therei n; 1 t Figure 2 is a verticallongitudinal section taken on the line 22 of Figure 1,-and

Figure 3 is a vertical transverse section taken on the line 38 of Figure2.

-The device shown comprises; a base 5 which may be of a suitableinsulatingcomposition or material and has its undersurface recessed at 6and 7. p

The heating element per se, comprises the usual or any suitable electriccoil 8 in the form of a helically wound wire of proper characteristics.The wire or coilSis wound or wrapped helically upon a relatively thinmetal tube 9 with a layer or wrapping 10 of mica or other suitablematerial between the coilor wire 8 and the surface of the tube 9 forinsulating the coil electrically from the tube. The coil 8 may in turnbe surrounded or enclosed externally by a layer 12 of heat insulatingcomposition which may be put on in a plastic conditionerotherwise placedabout the coil and which may be of any suitable material having thedesired heat insulating characteristics. A

y The heating elementis enclosed in a housing 15. This housing 15 may beformed of suitable sheet metal rolled or otherwise shaped to form acentral compartment 16 of generally circular cross section forsurrounding the heating means and-a'pair of lateral or side compartments17 and 18 extending longitudinally along opposite sides of thecompartment .16 and having their in teriors in commu nieationwith theinterior of the central compartment 16 throughopenings 20 extendinglongitudinally along the common sides of the compartment 17 andcompartment '16 and compartment *18-and compartment 16, respectively,and formed,

exairiple, by leaving the opposite rolled .sidesof the compartment lbspaced the desired amount in the formation of thehous- The ioppositeends of the intermediate compartment 16 may extend beyondthe ends of theside. compartments 17 and 18, as indicated at 22 and the sides of theseextend ingends 22mayrbe at least more nearly closed, as indicated at 23.The extending ends22fit snugly within the external flanges moved.

The cuppedportions 2 L also finish the opposite ends of the intermediatecompartment and close the ends of the annular space between the tube 9and the surrounding wall of'the housing. The-end brackets 25 may haveangular feetsecured to he base 5, as by means of bolts 32, the heads ofwhich may engage'in the recesses 6 and 7 toreanove them irom thesupportmg surface;

Suitable insulated conductors provided with aphig'or other connector 36for elec trical connection with the usual Edison or other outlet, enterthe recess '7 in the base throughan opening 38 and extend from therecess '7 out through an opening 39 and up through the wallet theintermediate housing 15yand into the annular space between said wall andthe heating means in said compart-merit 16 and there have suitableelectrical 'connection" with the coil 8 for the usual purpose. Theportions of the conductors 35 extending from the base 5 tothe housing 15maybe enclosed within asleeve 40 Whiclrmay be a separate sleeve set inplace or'it may be formed integral "with either of the parts.

The end brackets .25 may have lateral prongs or hooks for supporting theirons when not in use.-

In use, connection is made to the desired outlet and the circuit throughthe heating coil is turned on. The iron 50 which may, 01" course, be ofthe curling. Marcel, waving or other type, may be inserted into thecentral compartment 16 until heated the proper or desired amount foruse. To prevent overheating, which has heretofore frequently resulted inburning or other injury to the hair, or has necessitated cooling of theiron before applying it to the hair; the iron, after heated the properor desired amount, is withdrawn from the central compartn'ient 16 andinserted into either of the side compartments 17 or 18, whichcompartments maintain the iron at the proper and a substantially uniformtemperature. The compartments 1? or 18 are heated by radiation from theheater in the compartment 16 so that the loss by radiation of the entiredevice is very small and the current consumption is minimized. Thecommunication between the compartment 16 and compartments 17 and 18 isrestricted and the compartments 17 and 18 will not overheat the iron, asmay the compartment 16.

The iron may be used, and Where the temperature does not fall very much,placed back in one or" the side compartments 17 or 18 to maintain it atthe desired temperature. here a tter use, the tempo ature of the irondrops appreciably. it may be inserted into the central compartment 16and again brought up to the desired temperature, whereupon it may beremoved and placed in one of the side compartments 17 or 18 andmaintained at that temperature.

It should be noted that the iron 50 may be placed or inserted into thecompartment 16 from either end and that the irons may also be placed orinserted into either of the side compartments 17 or 18 from either end.In Figure 1, I have shown two irons, one inserted into one sidecompartment from one end and the other inserted into the other sidecompartment from the other end. Such use adapts the device for use bytwo operators at different sides or ends of the heater.

The side compartments 17 and 18 are shown above the center of thecentral com partmeut 16 to expedite the heat transmission thereto, butthis may, of course, be varied, as desired. It is also to be understoodthat while I have described the dos tails of the heating element per se,and various other details, that these are merely descriptive of theparticular embodiment of the invention shown and may be varied withinthe scope of the appended claims.
